Specification of Letters Patent. Pat t d D 28 1915 Application filed April 26, 1909. Serial N 0. 492,229.

To all whom it may concern:

Be it known that I, WILBURN N. DENNI- sort, a citizen of the United States, and a resident of the borough of Merchantville, State of New Jersey, have invented certain new and useful Improvements in Talking- Machines, of which the following is a speci fication;

The main objects of this invention are, to provide in a pneumatic talking machine, improved means for conveying compressed air to the sound box; to provide a pneumatic talking machine of graceful appear ance, and of -.-compact, strong, and durable construction; and to provide other improvements as will appear hereinafter.

In the accompanying drawings, Figure 1- is a fragmental side elevation partly in vertical section, of a talking machine const ructed in accordance with this invention; Flg. 2 a top plan view of a portion of the same; andFig. 3 an enlarged fragmentary top plan view partially in transverse central section of a portion of the same.

Referring to the drawings, one embodiment of this invention comprises the usual casing 1, rotatably mounted upon which is the usual turntable 2 for carrying a disk p. record. Rigidly secured to the outer surface bearing for the larger or pivoted end of the at its outer end a' pneumatic sound box 11 of one side of the casing is a fixed support which is shown in-the drawings as a rigid hollow bracket 3 which is curved outwardly and upwardly from the casing and the upper portion of which extends vertically and terminates in an. inwardly extending substantially horizontal lug 5, the inner surface of which is concave and substantially semicylindrical about a,vertical axis.

Rigidly secured within the semi-cylindrical lug 5 and cdaxial therewith is a ring 6, forming with the spider- 21 a removable swinging sound conveying arm, the ring belng held In fixed position by means of screws 7 extending radially through the lug 5, and

threaded into the ring.

Mounted within the ring 6 to swing over the' record in a plane substantially parallel to theplane of the record surface, and depending downwardly from said ring is the larger end of a swinging tone arm carrying operatively connected thereto by means of the vU-shaped tubes 9 and 10, having them opposite ends connected to said arm and sound box respectively, said sound box be-. mg so secured to swing in a plane substantially transverse to the plane of the turntable or record surface.

In the form of my invention illustrated 1n the drawings, the swinging tone arm is shown as a tapering sound conducting tube 01 member Shavingjointed thereto the U-shaped tube 10, and said arm is supported by means of a hollow pivotal memberor projection 12 preferably rigid with said arm and depending downwardly therefrom in alinement with the axis of said ring 6. The lower portion 13 of the hollow pivotal member 12 is cylindrical and reduced in size, forming with. the upper portion an annular shoulder 14, and the reduced-portion forms a cylindrical journal which fits snugly but turns freely in a cylindrical bearing provided therefor through the upper and lower 'walls of the bracket. The said bearing is surrounded upon the upper side of the bracket by an annular boss 15 integral with the bracket against which the shoulder 14 of the said member 12 engages. The lower end of the said pivotal member extends through the bracket and is surrounded by an annular boss 16 integral with the bracket, against which engages a nut 17' threaded upon the end of the said pivotal member. The upper portion of the said pivotal member 12 is provided with an axial socket in which is erture providedtherefor in an upper spider I 21 which fits tightly in the ring 6 rigid with the bracket 3. The undersurface of the upper spider 21 engages against the upper end ,of the said sound conducting tube 8.

An amplifier or horn 22 is provided which has at its inner end an outwardly extending annular flange 23 which engages rotatably in air-annular recess or seat 251 provided therefor in the upper side of the fixed ring 6.

The amplifier is held rotatably in position by means of a flat segmental plate 25 which fits over the upper' end of the bracket and is provided with a segmental inwardly extending projection 26 which fits centrally around the rear side of the amplifier in a segmental recess 20 provided therefor in the upper surface of the annular flange of the amplifier, the bottom surface of the projection contacting against the bottom wall of the recess. The segmental projection extends through an arc of about 90 degrees, while the recess in which it engages extends through an arc of about 180 degrees, thus the above description of the construction shown in the drawings. The plate 25 is fixed upon the end of the bracket by means of a screw QT-extending through the plate and threaded into the bracket, and a pin 28 rigid with the plate and projecting into an aperture provided therefor in the bracket.-

For connecting the U-shaped tubes 9 and 10 to the tapering sound conducting tube 8,

the said tube 8 is provided with a transverse sleeve 30 secured thereto in any suitable manner, the end of the said tube ,8 projecting for a short distance within the said sleeve 30. Fitted within the sleeve 30 is a bushing 31, the ends 31 of which fitsnugly within the said sleeve flush with the ends of the sleeve, and the said bushing 31 is reduced in diameter intermediate of its ends to form an annular passage 32 between the bushing and the sleeve. The end of the sound conducting tube 8 is open and fits closely in an aperture provided therefor in the bushing 31, and holds the bushing in a fixed position. the end edge of the arm 8 terniinating flush with the inner cylindrical surface of the said bushing 31.

One of the U-shaped tubes 10, which may be referred to as the delivery U-tube, projects entirely through and is fitted to turn in the bushing 31, and is provided upon one side of the bushing 31 with an annular flange contacting against the adjacent ends of'the bushing and sleeve. The end of the delivery U-t'ube projecting through the bushing 31 is provided with external screw threads 36 ad acent and upon the outs de of the bushin and anut W i nga ing the H Z" c threads 36 and contacting against the adjacent ends of the said sleeve and bushing a) draw the flange 35 of the U-shaped tube into close engagement with the opposite ends of the sleeve and bushing. to hold the U-shaped tube,rotatably in position and to seal the ends of the annular passage 32 between the sleeve and the bushing.

The extreme end- 38 of the U-shaped delivery tube 10 is reduced in diameter from the threads 36 outwardly to permit of the free passage of the nut 37 over the reduced end and to receive the adjacent end of the other U-shaped tube 9, which may be referred to as the supply U-tube and which telescopes snugly over the reduced end 38 of the U-shaped delivery tube 10. The interior of the U-shaped delivery tube 10 com municates with the tapering sound conducting tube 8 through an outlet aperture l0 provided therefor in the side of the said tube 10, the outlet registering with the open end of the sound conducting tube 8 when the sound box is in operative position.

A partition ll is provided within the U- shaped delivery tube 10 betweenthe outlet 40 and the reduced end 35 of the said tube 10, dividing the interior of the" said U-.

shaped tube into two chambers, 43 and t4, the latter chamber 4% communicating with the other U-shaped tube 9. When the sound box is in operative position. the latter chamber 44: also communicates with the. annular chamber surrounding the bushing 31, through diametrically opposite inlet apertures 4:5 in the walls of the U-shaped tube 10 registering with corresponding apertures 46 in the surrounding bushing 31.

I or supplying compressed air or other fluid to the sound box through the U-shaped supply tube 9, a supply pipe 50 is rigidly connected at its outer end to the under side of the sleeve 30 through which it communicates with the annular passage 32 surroundmg the bushing 31 within the sleeve. The

pipe extends parallel and close to the under side of the taper tone arm 8. rigid therewith, and the inner end of the pipe 50 is fitted radially into the hollow pivotal member' .12 supporting the radial tone arm and communicates axially downwardly through the said pivotal member, which is made hol low for the purpose. and through the diametrically opposite transverse apertures 51 through the said pivotal member with the i interior of the bracket 3. The portion of the said pivotal member 12 in the interior of the bracket between the upper and lower walls thereof. is slightly reduced in diameter to facilitate the construction of the same. and is sin-rounded by a free space to facilitate communication between the said pivotal member and, the interior of the bracket.

The interior of the hollow bracket 3 is I supplied with compressed air by means of a pipe 53 extending from the interior of the casing 1 through the side of the casing and threaded into the bracket to communicate with the interior thereof. A mechanism for compressing the air is preferably located in the casing 1.

As diagrammatically illustrated in dotted lines in Fig. 1 the fluid compressing means, or fluid supplying means,

' maybe employed as a source of air supply.

This arrangement provides a construction in Ich the conductor, communicating w1th the sound box, is jointed or articulated o-r'v articulative, both at the point of connection between the U-shaped supply tube 9 and the tube 50, and between the tube 50 and the hollow bracket or support 3, and since the H, JOlIltGClat one end on an axis coincldent with articulated air supply tube is pivoted or the axis of the pivotal support on which the tone arm 8 swings, and since the U-shaped supply tube 9 swings on an axis coincident with or in alinement with the axis of the sleeve 30, the means for conveying or conducting the fluid for operating the sound box, offers substantially no resistance to the free. movement of the tone arm 8, as it swings over the tablet, or to the vertical movement of the U-shaped tubes and the sound box, when the device is employed in a machine for reproducing or recording sound. I

In the operation oflthis device, the compressed air is forced through the pipe 53, bracket 4, hollow pivotal member 12, pipe 50 and into the annular chamber 32 between the sleeve 30 and the bushing 31 fro-m whence, when the sound box is in operative position, it passes through the oppositely disposed apertures 46 and 47 into the chamber 44 in the end of the U-shaped delivery tube 10 and thence through the U-shaped supply tube 9 into the sound box. After passing through the sound box and being set into vibration thereby, the air passes through the U-shaped delivery tube 10, tapering sound conducting tube 8 and into the amplifier. By arranging or disposing the apertures 46 and 47v between the chamber 44 in the end of the U-shaped delivery 10, and the annular chamber 32 between the sleeve 30 and the bushing 31, the effect of the air passing through these oppositely disposed openings is to balance the pressure on thesides of the tube 10 within the bushing; that is to say, the air passing through one opening does not tend to press the tube 10 against the opposite side of the bushing 31 in which it is inclosed, and, therefore, all friction which would otherwise result from the pressure of the air passing through said apertures is entirely eliminated, and the sound box is substantially as free to swing transversely to the record about the sleeved end of the tube 10 as it would be if there was no' difference of pressure between the air in the saidtube and the outside atmosphere. Moreover, the air, by passmg through oppositely disposed apertures in the chamber 44, flows smoothly through the tube 9 to the sound box. A similar construction is em ployed in connection with the air passages in the hollow pivotal member 12, inwhich the apertures 51 put the interior of said member into communication with the interior of said bracket 3. This feature of the A balancing of the air, or currents of air in the fluid conducting tubes is one of the'features of my invention. The sound box may be rotated upwardly about the axis of its supporting sleeve 30 and brought to rest in an inverted inoperative position upon the upper surface of the taper arm 8, and when in this position it is evident that the apertures 45 and 40, controlling the inlet and outlet of compressed air through the U.-shaped tube 10 will be closed, thus stopping the flow of fluid current through the sound box.

In the arrangement of the parts-above described, itis plain that the sound box is spaced or separated from, but operatively connected to, both the support for the sound conducting arm 8 and the source of air supply, by the sound conducting arm 8. It is also clear thlit the fluid is conducted to the sound box through a conductor consisting of a plurality of members jointed or articulated together, said members being in a balanced relation to each other with respect to the tendency of the fluid to press said members against each other transversely at the joints, or articulations. The members of eachadjacent pair of said jointed members recorder to the free oscillation of the 'sec-' tion of the conductor between the air supply tube 50 and the sound box. To remove the sound conducting tube 8 from the bracket 3 it is only necessary to remove the screws 7 and free the ring (3 from the upper end of the bracket, and to remove .the nut 1?, whereupon the tube8 and its pivotal support 12 may be bodily lifted out of the bracket, the pivotal member sliding freely through the opening in the bracket. This arrangement provides a construction in which the swinging sound conducting tube 8 may be described asmounted in the bracket in two bearings, one of'which (the ring 6 having the spider 21) is removable from the bracket, and the other (the walls of the openings in the bracket through which the pivotal member 12 extends) is permanently in the bracket.

While'in the specification and claims the expression-pneumatic sound box is used, the invention is not limited to a sound box iso the medium employed, and the expression pneumatic soundv box is intended to refer to any sound box through which any suitable fluid is passed, and upon which fluid the undulations are impressed by the vibration of a suitable mechanism primarily operated by undulations corresponding to sound waves.

Although only one form in which this invention may be embodied has been described, it is obvious that many changes might be made in the construction set forth without departing from the spirit of this invention, or the scope of the appended claims.
